` IMPROVMENT IN GRAINeRGISTERS.

Specification forming part of Letters Patent No. [86,6l4, dated January23, 1877; application led June 29, 1876.

To all whom it 'may concern: y

Be it known that ,I, LEMON POOLE, of the city of Springfield, countyofGlarke, and State of Ohio, have invented a new and useful Improvementin Grain Measures and Registers, which improvement is fully set forth inthe following specication, reference being hadto the drawingsaccompanying this specification.

The object of my invention is to measure with accuracy and registercorrectly all the grain which may bethrashed and delivered from aseparator, with less labor andl time than can be done by any registersnow in use; also,

to furnish for this purpose a combined measure and register which issimple anddurable, and which can be either attached directly `to themachine, oroperated independently of it, receiving its grain fromconnecting conveyers.

Figure lis a front elevation of my measure and register. Fig. 2 is a topview of the same. Fig 31s a plan viewof one pair ofthe valves. I Fig. 4is a perspective View ofthe upper pair of cut-offs. Fig". 5 is a planv'iew of the lower l pair of cut-offs. Fig. 6 gives a plan view of theupper eut-oli' Hand valve Gopen. y Fig. `7`

t Fig. 7.

Both the cut-offs are cast hollow. The valve of each is similar.

A isthe register,'which is :shown with its door open,to show theinterior mechanism.

. t B is the cylinder, `for receiving and measuring l the grain. `Tothefront of its upper end is Y attached the` register A. The cylinder ismade of sheet metal, and, for convenience of `access to its interiorparts, is made in two sections, which are held together by projectinglugs, and bolts and nuts. A conical cap,

` b, isslipped on thelower end, forcontracting "the discharge of grain.

This is provided with `hooks cc, for attaching `the mouth of a sack toreceive the measured grain. The cylinder B is shown with a sectionbroken out, to show its interior.

' A vertical shaft, C, extends through the center ofthe cylinder B, itslower end being pivoted upon the point of an adjustable screw,

d', which is inserted up through the middle of the bridge-tree D. Theupper end of the shaft projects above the top of B, so as to give roomfor the crank-lever B and its coiled spring b.

`The shaft turns in a cross-piece under the top ,plate E.

Two pairs of valves, G, Fig. 3, are mounted upon the shaft. These valvesare of thin metal, in the form of a at disk, with one-sixth like thescrew of a propeller, but having-the upper angle of its blade carrieddown vertically. The object of this is to allow of the attachment of aflat brush in case the wear of the cut-off and valve renders thisnecessary, as the upper cut-off and valve are subjected to "much, thegreatest wear. f is the straight side, which forms the face of the uppercutoff. The lower one, I, is constructed with inclined sides, decreasingtoward the center of the cylinder. These cut-offs are also in pairs,with a middle collar, and are 'made of thin cast metal. I has its sideshighest next the inner wall of the cylinder, and they slope from acentral rib or angle down to the edge of the holes formed by the openingof the valves, so as to facilitate the discharge of the grain lying onthem. This cut-off is also seen in dotted lines, Fig. 1. Each pair ofcut-offs are of the same area at the base as the surface of the valves,being equal to two-thirds of the area of a cross-section of cylinder B,leaving one-third for the two openings in each.

` The valves are secured to the shaft by setscrews. They are at rightangles, or `nearly so, with each other, and the cut-offs are placed inthe same manner, so as toY allow of their each movement.

openings being coincident with each other in opening. The register A isconstructed with a large dial-wheel, a', with teeth of ratchet! shape.Below this are fastened two spools, which carry a tape, c', wound uponthem, on which is numbered the bushels of grain meas-V ured. The greatwheel a has a pin, c, prov jecting from its side, which strikes a toothof Wheel b on the inner end of spool l below it at every revolution. Asmall Wire, c", extends across the top of the tape to indicate thefigures to be counted. The tape is drawn to the left, rolling up onspool 1, and unrolling from off spool 2. At each revolution of thedial-wheel a the tape c moves the distance of one space between itsfigures. teeth of the dial-wheel project through a slot in the top ofthe register-box just far enough to allow the end lot the flat spring eto catch one tooth and turn it one space when the crank-lever B (whichcarries this spring) is operated from left to right. The spring e isriveted at its back end on the top ot' lever B, and its forward end isbent down below it to allow it to strike the tooth of wheel a at eachmovement. The crank-lever B is turned from stop k till it reaches stop7c', when the grain is discharged through the valve-openin gs from themeasure part of B, and the figures on wheel a' indicate the tally. Thecoiled spring b', which iswound around the upper end of shaft O, isextended out along lever B through an eye-bolt near its handle. Itthrows the lever back to stop k after each tallying movement.

The tape c may be long enough to mark one thousand bushels, or evenmore, if required. The shaft of spool 2 projects beyond its frame, andis squared, so as to allow ofthe tape being rewound on it by the use ofa key. A spring-pawl, p, holds the dial-wheel a. after One side of thetop of B is hinged to the other part so as to form a lid.

A square, hole, c', is. seen in it, Fig. 2, through which the spout ofthe elevator or conveyer discharges its grain into the cylinder from theseparator. The space above the upper valve TheA may contain more than ahalf-bushel, but the space between the upper and lower valves isintended to contain exactly this quantity.

In operating my device care is taken to allow the cylinder to ll beforemoving lever B. moving wheel a as before described) till arrested bystop k closing the upper valve and cutting olf from the middle ormeasure part B any grain that may be above it, and at the same time thatthe upper valve is closed the lower one opens, so as to discharge thegrain measured. l l are lugs which extend out from the cylinder at thejunction of the upper and lower sections. They are fastened together bybolts and nuts m m.

A lock may secure the door d, so as to prevent the register from beingtampered with when used. The valves can be easily adjusted to theircut-offs by lmeans of the screw d', which raises and lowers-the shaft G,so as to tighten or loosen them. This screw is provided with a jam-nutbelow the bridge-tree D to secure it in place.
